MECHANISM FOR PRODUCING RECIPRQCATING MOTION.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed April 1, 1906. Serial No. 258,264.

, Ohio,) have invented certain new and useful Improvements in 1Mechanism for Producing Reciprocating Motion, of which the following is a specification.

This invention, pertaining to improvements in mechanism. for producing reciprocating motion, will be readily understood from the following descriptiomtaken in connection with the accompanying drawings, in which Figure 1 is a side elevation of a construc tion exemplifying the present invention as applied to a metal-planing machine; Fig. 2, an end elevation of the same; Figs. 3 to 6, inelusive, diagrams illustrating a few of the many modifications to which the invention lends itself.

In the drawings, and giving consideration for the present only to Figs. 1 and 2,1 indicates the bed of a metal-planing machine; 2, the table of the same; 3, one of the housings; 4, one of the shafts pertaining to the usual driving m'phanism of the planer and serving when turnedr'in one direction or the other to bring about a reciprocating motion of the planer-table; 5, a driving-shaft mounted in suitable bearings and adaptedto have motion imparted to. it continuously in one direction by any suitable means-as, for instance, a beltpulley upon the shaft or a motor connected with it; 6, a bevel-gear on shaft a; 7, a shaft suitably supported in bearings at right angles to shaft 4; 8, a bevel-pinion fast on shaft 7 and gearing into gear 6; 9, a pulley fast on shaft 7; 10, a counter-shaft disposed infixed bearings. parallel with shaft 7; 11, simple gearing connecting shafts 10 and 7, whereby those shafts turn in relatively opposite directions; 12, a pulley fast on shaft 10; 13, a pulley fast on shaft 5 in the plane of pulley 9; 14, a pulley fast on shaft 5 in the plane of pulley 12; 15, a frame so mounted thata portion of it is capable of movement in a path at right angles to shaft 5, this frame being illustrated as swinging upon shaft 5; 16, a part connected with the frame 15 to serve in swinging it either director by communication from other appropriate mechanism; 17, a pair of belttightening pulleys carried by the swinging frame, one in the plane of pulleys l2 and ld and the other in the plane of pulleys 9 and 13; 18, a slack belt engaging pulleys 9 and 13 and adapted to have one of its sides engaged by one of the belt-tightening pulleys; 19, a slack belt engaging pulleys l2 and 14k and adapted tightening pulleys upon the side opposite that of the first-mentioned tightening-pulley.

Normally shaft 5 is 'in motion, both beltbelts are running idly, and the planer mechanism at rest. If the swinging frame be pushed inwardly toward the housing, belt 19 will become tightened and the planer-table will be driven in one direction. If, now, the frame be swungoutwardly, then the tightenening-pulley will go into action and tighten belt 18 and in an obvious manner cause the direction opposite to that produced by the.

other belt each belt has its driving-pulley conto be engaged by the other one of the belttightening pulleys are out of action, and both ing-pulley just mentioned will be relieved and belt 19 be left slack and the other tight M planer-table to be drivenin the opposite di nected with separate bevel-pinions, the two bevel-pinions being opposite each other, so

that while turning in the same direction they produce opposite effects on gear 6..

In each of the above examples it has been assumed that the planer-shaft 4 is at right angles to shaft 5, constituting the drivingshaft, and in' this arrangement the bevelgeared construction comes nicely into play; but in many cases the bevel-gearing is neither present nor desirable. In Fig. 4 is illustrated a modification in which the driven pulleys of the two belts are on shafts 25 and- 26, connected by simple gears 27, so that they turn in opposite directions. These two shafts 25 and 26 may well betwo of the ordinary shafts found in the transmitting-train ofa metalplaner. In the modification now being described instead of moving the belt-tightening pulleys to the belt the belts'are moved to the belt-tightening pulleys. Shaft 29 is in box 30, shifting on bracket 31, this shaft carrying 1 the driving-pulley 28 for the two belts. The belt-tightening pulleys 33 and 34: are in a fixed position, and-by shifting the shaft 29 either belt can in-an obvious manner be other tightens either belt selectively. In this ing frame 22, having its axis of oscillation at shaft 5, connected by gearing 21 with the two pulleys.

By rocking the frame 22 either of the driving-pulleys 23 or 24: may be caused to tighten its belt and make that belt effective. Again, in Fig. 6 the two driving-pulleys 37 for the main belts are carried on a swinging frame 36, which being swung one way .or the arrangement motion is imparted to the shaft of pulleys 37 by means of belt 38 from driving-pulley 35, located at the axis of oscillation of the swinging frame. v

It is to be observed that all of the examples are characterized by the pair of normally slack belts moving in the same direction, and thus capableof deriving their motionsfrom a single shaft, their reversing effect being l due not to diversity of belt action, but to the reversing character of the transmitting mechanism between the terminal. pulleys of the belts and the mechanism to which reversing motion is to be imparted.

I claim as my invention 1. In driving mechanism for producing reciprocating motion, the combination, substan tially as set forth, of a'shaft to which motion is to be transmitted in selective directions, a pair of driven pulleys, mechanism connecting said driven pulleys with such shaft in such manner that the turning of the two pulleys in one direction corresponds with reverse direction of motion of said shaft, a driving-pulley in line with each driven pulley and arranged for rotary motion in a single direction, an open slack belt connecting each of the driving-pulleys with one of the driven pulleys, and means for tightening said belts alternatively.

2. In driving mechanism for producing reciprocating motion, the combination, substan tially as set forth, of a shaft to which motion is to be transmitted in selective directions, a pair of driven pulleys, mechanism connecting said driven pulleys with such shaft in such manner that the turning of the two pulleys in one direction corresponds with reverse direction of motion of said shaft, a driving-putl'ey in line with each driven pulley and arranged for rotary motion in a single direc tion, an open slack belt connecting each of the driving pulleys with one of the driven pulleys, and a shifting-pulley device for tightening said two belts alternatively.
